American Airlines has notified online travel customers that Expedia and Orbitz no longer feature American Airlines’fares. Meanwhile Kayak and Priceline gain American Airlines’ favour.

With the events of this week, American Airlines has two favorite online travel websites — Kayak and Priceline.

The airline has notified online travel customers on the AA.com homepage that “Expedia and Orbitz no longer feature American Airlines’fares.”

When you click on the provided link, American Airlines states: “Expedia has chosen to no longer feature American Airlines fares on its website. Customers looking to compare flights or fares online should visit other travel sites such as Kayak.com or Priceline.com for the most accurate and up-to-date information, or you can always find our Lowest Fares Guaranteed and No Online Booking Fee at AA.com. American flights can also be purchased from a wide range of accredited travel agencies across the globe.”

American Airlines yesterday pointed to Priceline and Kayak as booking alternatives in a statement, but has now highlighted these online travel alternatives on AA.com.

And, of course, American Airlines notes that its fares are no longer available on Orbitz.com and other websites powered by Orbitz.com. The latter would include Orbitz for Business.
